- Abstract
The effect of ferrous ions on the molecular weight and molecular weight distribution of PCE is investigated by Gel permeation chromatography (GPC). The effect of ferrous ions on the dispersion properties of PCE is measured by the fluidity of cement pastes. The results indicate that ferrous sulfate adopted at the initiation system can accelerate the reaction and ensure the reaction rate at 5 -10 . Ferrous sulfate dosage should be 0.02 wt% of the total monomers, which insures the best initial dispersibility and dispersion retaining ability of PCE.
